ADMLogger is a log analyzing engine. Using this
core, users could easily build upon it with
plugins. With very little Perl programming
knowledge, it may become a powerful tool in a
System Administrator's toolbox. ADMLogger creates
email reports that can be formatted plain text or
full HTML, which is up to the plugin designers to
support. The main system has an HTML preference,
so if your plugin ignores it, so be it. ADMLogger
will also remove all filtered entries from the
main syslog file into a second file so your other
entries are more noticable.

AXIGEN is a fast, reliable and secure mail server
with an open architecture. It is designed for easy
management and allows full control of the email
traffic from a central Web/CLI admin module.
AXIGEN provides ESMTP, IMAP, and POP3 services and
has been tested with standard mail clients. A
special Webmail module enables email access and
delivery from Web browsers. During the evaluation
period, users are provided with full technical
support.

AirSAM is a desktop GUI that compliments the Web
based Snort Alert Monitor. AirSAM gives up to date
insight into who might be attacking your network.
The ultimate goal is to give audio/visual cues
right at the time of the attack. AirSAM is an
Adobe Air application and should run on Mac OS,
Linux, and Windows.

AlarmMon is an alarm monitoring system for TCP/IP
networks. It consists of an "alarm" client, an
"alarmsvr" server, and several agents that work
with a central registration database. It can
track the status of verious services, including
BIND, Sendmail, and modems, and send
notifications by email, SMS, or pager.

Alerttail monitors a given file and executes a
list of actions when a user-defined text pattern
has been written to the file. For example, the
user can pop up a GTK notification window when a
certain message is written to a log file. Actions can be alerttail built in actions (GTK notify action, geoipLocalization action, or filtering text action) or a custom user defined shell command action. A Qt 4 GUI frontend helps with configuration.

Analog PHP is a short and simple logging package for PHP 5.3+ based around the idea of using closures for configurability and extensibility. It functions as a static class, but you can completely control the handling of log messages through closures (aka anonymous functions), and it also comes with a dozen pre-written handlers. It is well-documented, with examples for each type of log handler, and ultra-concise. The core is literally only 43 lines of clear, non-obfuscated code, and the whole is only a fraction of the size of comparable packages (for example, 293 total lines vs 1021 for Monolog).

Synapse is an ESB engine and XML router built
completely on open standards. It is a mediation
framework for XML messages and Web services that
allows messages flowing through, into, or out of
an organization to be mediated, including aspects
such as logging, service lookup, performance
mediation, versioning, failover, monitoring, fault
management, and tracing.
